Fentanyl Intranasal for Retinopathy of Prematurity Screening in Preterm Infants

Retinopathy of prematurity (ROP) screening is an essential part of the care of preterm infants. Despite the routine use of standard comfort measures, the examination remains associated with moderate-to-high pain intensity scores in many infants. Repeated exposure to untreated or undertreated procedural pain in preterm infants has been associated with adverse short- and long-term effects, highlighting the need for additional evidence-based pain management strategies.

Intranasal fentanyl has several characteristics that make it a promising option for procedural pain management. It has a rapid onset of action, is easy to administer, avoids the need for intravenous access, and has been shown to be effective and well tolerated for procedural pain in older infants and children. Emerging neonatal evidence, including randomized controlled trials, suggests that intranasal fentanyl may reduce pain during ROP screening, but additional high-quality evidence is needed to establish its effectiveness and safety in preterm infants.

This randomized, double-blind, placebo-controlled clinical trial will evaluate whether intranasal fentanyl, when used in addition to standard comfort measures, reduces pain during routine ROP screening while maintaining an acceptable safety profile. The study is designed to provide high-quality evidence to help determine whether intranasal fentanyl should be considered as an additional option for pain management during this necessary neonatal procedure.

The findings from this study may help improve pain management for preterm infants undergoing ROP screening and contribute to future evidence-based clinical practice guidelines for neonatal procedural pain management.

Inclusion criteria

• Preterm infants born ≤31 weeks gestational age and/or with birth weight <1250 g
• Scheduled to undergo routine retinopathy of prematurity (ROP) screening as part of standard NICU care
• Clinically stable at the time of screening, defined as not requiring acute resuscitative support (no bag-mask ventilation, intubation, or chest compressions within the preceding 24 hours) and maintaining stable cardiorespiratory parameters on baseline respiratory support
• Written informed consent obtained from a parent or legally authorized representative

Exclusion criteria

• Congenital anomalies or conditions affecting the nasal passages that would interfere with intranasal drug administration
• Receipt of systemic opioids, benzodiazepines, barbiturates, or other sedative/analgesic medications within 24 hours prior to the ROP examination
• Known hypersensitivity or prior adverse reaction to fentanyl
